1. What is the primary responsibility of an NDT Level II technician?
A. Establish company-wide NDT policy
B. Develop all NDT procedures without approval
C. Perform and interpret NDT examinations according to qualified procedures
D. Approve all engineering designs
Answer: C. Perform and interpret NDT examinations according to qualified
procedures
Rationale: A Level II technician is generally qualified to set up equipment,
perform examinations, interpret and evaluate indications, document results,
and work within approved procedures and applicable requirements.
2. Which NDT method is most suitable for detecting surface-breaking cracks in
a nonporous ferromagnetic component?
A. Radiographic testing
B. Ultrasonic testing
C. Magnetic particle testing
D. Visual testing
Answer: C. Magnetic particle testing
,Rationale: Magnetic particle testing is particularly effective for detecting surface
and near-surface discontinuities in ferromagnetic materials.
3. What is the main purpose of a written NDT procedure?
A. To eliminate the need for technician training
B. To replace applicable codes
C. To specify the controlled requirements for performing an examination
D. To establish material prices
Answer: C. To specify the controlled requirements for performing an
examination
Rationale: The procedure establishes the examination technique, equipment,
settings, calibration requirements, acceptance criteria references, and other
essential controls.
4. Which NDT method uses high-frequency sound waves to detect internal
discontinuities?
A. Magnetic particle testing
B. Liquid penetrant testing
C. Ultrasonic testing
D. Visual testing
Answer: C. Ultrasonic testing
Rationale: Ultrasonic testing introduces high-frequency mechanical waves into a
component and analyzes reflected or transmitted sound energy.
5. What is the purpose of calibration in NDT?
A. To increase material hardness
B. To repair discontinuities
C. To verify that equipment produces accurate and reliable measurements
D. To eliminate all indications
,Answer: C. To verify that equipment produces accurate and reliable
measurements
Rationale: Calibration or performance verification confirms that the equipment
is operating within specified requirements before measurements are relied
upon.
6. Which discontinuity is generally considered planar?
A. Porosity
B. Slag inclusion
C. Crack
D. Gas pocket
Answer: C. Crack
Rationale: A crack has a relatively small opening compared with its length and
depth, making it a planar-type discontinuity.
7. What is the primary purpose of visual testing?
A. To measure internal density
B. To detect only magnetic discontinuities
C. To examine surfaces and features for visible conditions or indications
D. To determine alloy chemistry
Answer: C. To examine surfaces and features for visible conditions or indications
Rationale: Visual testing can identify surface conditions, dimensional problems,
workmanship issues, corrosion, cracks, and other observable conditions.
8. Which method uses a liquid that enters surface-breaking discontinuities
through capillary action?
A. UT
B. RT
C. MT
D. PT
, Answer: D. PT
Rationale: Liquid penetrant testing relies on capillary action to draw penetrant
into open-to-surface discontinuities.
9. What is an indication in NDT?
A. Always a rejectable defect
B. Always a manufacturing defect
C. A response or signal that may indicate a discontinuity
D. A calibration block
Answer: C. A response or signal that may indicate a discontinuity
Rationale: An indication is an observable response from an examination. It must
be interpreted and evaluated before determining whether it represents a
relevant discontinuity.
10.Which term describes an indication that is caused by something other than
a discontinuity?
A. Relevant indication
B. Linear indication
C. Nonrelevant indication
D. Rejectable indication
Answer: C. Nonrelevant indication
Rationale: Nonrelevant indications result from component geometry, magnetic
flux patterns, surface conditions, or other factors rather than a material
discontinuity.
11.What is the primary advantage of radiographic testing?
A. It requires no radiation controls
B. It can provide an image of internal material conditions
C. It only detects surface cracks
D. It requires the component to be ferromagnetic
